  • Title: Motions of Alexis St. Martin's stomach.
    Author: Szurszewski JH.
    Journal: Fed Proc; 1985 Nov; 44(14):2894-6. PubMed ID: 3902509.
    Abstract:
    In addition to studies on the action of gastric juice, William Beaumont studied the motility of Alexis St. Martin's stomach. He documented the nature of fundal and antral motility and how antral contractions might convert an admixture of solid food and gastric juice into a uniform homogenous semifluid. Beaumont described forcible contractions of the antrum, closure of the pylorus during antral contraction, and the discriminatory nature of the pylorus. Beaumont may also have made the first observations of the gastric motor component of the interdigestive migrating motor complex.
